PETER GRAHAM MACGREGOR, OF NEW YORK, N.
Y., ASSIGNOR TO PYRENE MANUFAC- TURING COMPANY, A CORPORATON OF DELAWARE.
SIIRIAY-NOZZLIT.V
Application led December 18, 1918.
To all w/tom t may concern.'
Be it known that I, PETER G. MACGREGOR, a citizen of the United States, and resident of the city, county, and State of N ew York, have invented certain new and useful Improvements in Spray-Nozzles, of which the following is a specification.
This invention relates to nozzles of the type adapted to cause the fluid ejected therefrom to spread, or be distributed, over a relatively large area, nozzles of this type being generally known as spray nozzles.
The invention has for an object to provide an extremely cheap and eflicient spray nozzle for producing what is known as a whirling spray, the nozzle being more particularly intended for use in connection with fire extinguishing sprinkler systems, although not limited to such use.
For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.
In the accompanying drawings, which illustrate a preferred embodiment of the invention- Figure l is a side elevation of the nozzle.
Fig. 2 is an axial sectional view thereof.
ig. 3 is a cross section on the line 3 3 of Fig. 2.
Fig. 4 is a cross of Fig. 2.
Fig. 5 is a detail elevation of the gyrator.
As here shown my improved nozzle comprises a shell or casing l having a cylindrical chamber 2 extending from one end thereof to a point adjacent the other end. The terminal wall 3 of the chamber at the last mentioned end of the casing tapers inwardly, in Substanitally semispherical form, to a small central discharge orifice 4 therein.
The entrance end of chamber 2, or that opposite the wall 3, may have screwed thereinto a nipple 5 whereby the nozzle may be attached to any suitable conducting pipe or tube, while the portionvof the casing adjacent the wall 3 may be exteriorly screwthreaded to receive any suitable means, not shown, for closing the discharge orifice 4.
Loosely carried in the chamber 2 is the device for imparting a whirling motion to the section on the line 4h45 Specification of 'Letters Patent.
Patented Nov. 1, 192,1. Serial No. 267,289.
fluid passing through the nozzle. This device comprises a gyrator 6 consisting of a substantially solid body of circular cross section having a straight central portion and terminating at opposite ends in the similar truncated cones 7 and 8. The central portion is of a diameter to fit closely, but freely, 1n the chamber 2 and is formed on its periphery with a multiple thread, the thread shown in the present embodiment of the invention being a triple one of square formation. With this construction a series of spiral grooves 9 are formed in the periphery of the gyrator and form passages extending from one end to the other thereof, the bases of the conical extensions 7 and 8 joining the central portion inwardly of the grooves. The gyrator is also formed with a central axial passage l0 of somewhat smaller diameter than the orifice 4. A shallow recess l1 may be formed in the end of the nozzle adjacent the discharge orifice 4.
he gyrator is loosely mounted in the chamber 2 so as to be capable both of a rotary motion and a movement longitudinally into close contiguity to the end wall 3 of the chamber. The fluid passing through the nozzle flows along the spiral grooves in the gyrator and is thus given a whirling motion which, in combination with the general shape of the ends of the gyrator and of the end wall 3, causes the fluid to lift the gyrator from the discharge orice to provide a passage to the latter from the spiral grooves 9, the Huid being broken up into a ine spray as it issues from the discharge orilice 4.
l. A spraying nozzle consisting of a casing having a chamber formed therein and a restricted orifice through the end wall there` of, a gyrator loosely mounted in said chamber and free to move into close contiguity to the end wall of the chamber, said gyrator comprising a cylindrical body having a central passage therethrough and a spiral passage formed in its periphery, the forward end of said gyrator being conical and the opposed inner wall of the chamber adjacent the orifice being curved.
2. A spraying nozzle consisting of a casing having a chamber formed therein and a restricted orifice through the end wall thereof, a gyrator loosely mounted in said chamber and free to move into close contiguity to the end wall of the chamber, said gyrator comprising a cylindrical body having a spiral passage formed in its periphery, the forward end of said gyrator being conical and the opposed inner Wall of the chamber adjacent the orice being curved.
3. A spraying nozzle consisting of a cas-v ing having a chamber formed therein Withv the inner surface of the end Wall thereof tapering inwardly and of substantially semispherical form and provided with a centrally disposed discharge oriice, and a gyrator freely mounted in said chamber and adapted to move into close contiguity to said end Wall, the endof said gyrator ad'- jacent said end Wall being conical in form 15 and said gyrator being provided With a spiral passage formed on its periphery and With a central passage smaller than said county and State of 20
